This was a strong quality session. After a patient warm up, the interval work quickly moved into a sharper rhythm than planned, with several reps landing clearly inside 10K effort territory.
The best signal is that the pace progressed with confidence instead of falling apart. You touched 5:16, 5:08, 5:04, 4:57 and 5:08 /km across the main reps, which shows that the speed needed for Carrera Maya is already available.
The caution is the cost. Heart rate climbed hard in the second half and the session became more demanding than a controlled workout on paper. That is fine once, but the next step should absorb the quality and protect freshness.
Takeaway. Strong 10K signal, but respect the cardiovascular cost. The speed is there, so the next run should be a controlled Sunday long run that builds endurance without adding another hard effort.
Next step. Controlled long run. A steady aerobic long run to absorb the interval load and keep endurance moving. Stay controlled, avoid racing the finish.
